| 28 | * |
| 29 | * A chip is described by a set of unique devices. |
| 30 | * |
| 31 | * Each sub-arch has its own master list of unique devices and |
| 32 | * enumerates them by enum fsl_devices in a sub-arch specific header |
| 33 | * |
| 34 | * The platform data structure is broken into two parts. The |
| 35 | * first is device specific information that help identify any |
| 36 | * unique features of a peripheral. The second is any |
| 37 | * information that may be defined by the board or how the device |
| 38 | * is connected externally of the chip. |
| 39 | * |
| 40 | * naming conventions: |
| 41 | * - platform data structures: <driver>_platform_data |
| 42 | * - platform data device flags: FSL_<driver>_DEV_<FLAG> |
| 43 | * - platform data board flags: FSL_<driver>_BRD_<FLAG> |
